A novel computational fluid dynamics (CFD) models are been developed to study heat and mass transfer in the self-densification of metal hydride hydrogen storage tank. Energy equation and mass conservation with source term of hydriding kinetics are discreted based on finite volume method in 3-dimensional, and calculated by explicit formulation. The self-densification phenomenon involving particle size decreasing and falling of metal hydride powders leaving sparse and compact powders respectively, has been numerically analyzed by the CFD model. Heat and mass transfer with hydrogenation kinetics are studied at several degrees of self-densification phenomenon represented by porosity and proportion of self-densification area. The evolution of average temperature and hydrogen/metal (H/M) ratio with time are simulated at different degree of self-densification. The numerical results show that the degree of self-densification is the dominant factor which obviously influence the temperature and H/M ratio.
